2.3.8 Using Ambient Target Temperature Compensation
(OS533, OS534, OS523, OS524)
Use the Ambient Target Temperature Compensation
(AMB) Display Mode when high accuracy readings under both
of these conditions are required:
• The target has a low emissivity.
• The ambient temperature around the target is much
higher than the ambient temperature around the
infrared thermometer.
To set and activate the Ambient Target Temperature
Compensation Mode:
1. Pull the trigger and press the key to lock the
trigger. Set the emissivity to 1.0 (refer to Section 2.3.1).
2. Press and hold the key until the Average Display
Mode (AVG) appears.
3. Slowly move the thermometer so that the line of sight
sweeps across the area surrounding the target. The
thermometer measures the temperature at each point on
the surrounding area.
4. Read the average temperature value from the upper
display and record it here __________.
5. Press and hold the key until the Ambient
Temperature Display Mode (AMB) appears.
6. Set the AMB temperature found in Step 4 by pressing the
key or the key.
7. Press the key to enable the ambient target
temperature compensation. The icon appears
on the display.
To disable this mode, press the key again.
The icon disappears.
